Highway 105 River Bridge Cofferdams

As part of work on three new Highway 105 bridges that cross rivers between Brenham and Navasota, Texas, Stiver Engineering provided a sheet pile and tie rod shoring system design for the installation of the bridges’ bent foundation and abutment. The shoring plan included temporary wale sets, as well as a staging plan for accessing and excavating to the required depth to install the bent foundation and abutment. The final stage of work was a permanent sheet pile structure around the bent that was filled with low density concrete.
